Just some documentation about how to create a crontab:
Open a SSH connection to your server and sign in.
At the command line type:
vi crontab -e

The server will open the crontab file and shows all current entries. Enter "visual" if you're not allready in visual mode"

Use the following key combination: Shift + i

You will see the cursor move to the first line of the file. Put the cursor at the start of a new line and enter the job.
A cronjob typically looks like this:

0 0 * * * perl /home/site/cgi-bin/awstats.pl -update

This line means the following:

Execute perl /home/site/cgi-bin/awstats.pl -update every day at 0:00. I'll explain a bit more about this:

Every line looks like this:
1 2 3 4 5 command

1: minute to run at, * means every minute
2: hour to run at, * means every hour
3: day to run at, * means every day
4: month to run at, * means every month
5: weekdays to run, * for every day

replace "command" with the commando you wish to execute at the specified moment.

When you're finished adding the jobs, push the Escape button. Then type:

:wq

press enter to write and save the file.

The server will prompt with "Crontab installed" to confirm adding a crontab.
